A business-pleasure trip to Paris sets off a series of incidents that involve the Flaugherty twins in their first mystery.
A mysterious doll everyone seems to want, a legacy involving a cipher, and a ghostly knight haunting an old castle challenge Pat and Patty in their quest to help a newfound friend.
As they are plunged into many dangerous adventures, including a fourth-story rescue operation, they uncover clues that lead them to discover the Mystery at the Haunted Castle.
